You know you can use "she" or "her" more, right? Like not every sentence has to start with "reina", i can't count how many times I've read her name in one chapter.
Just a piece of advice for the author, do not interrupt the fight too much with these long dialogues between the mobs or telling as how great gilgamesh is, as it takes the person out of immersion and enjoyment to see the fight and ruins it
